"An OCC conquer the world game"? Isn't "OCC" the "one-city challenge", where your Singapore-like city-state launches the SS first?
Seems this would be REALLY hard as it is, but using it for conquest? Did you succeed?
I succeeded, though I was not 100% sure it would work in the beginning because seemed daunting. It is quite different to wipe out the world when you cannot ever capture an enemy city, and the planning takes a different mindset than normal.
Ultimately, I switched to Communism because the Vet. Spy was so valuable. This was expensive, because you can set 0% luxuries and have no unhappiness in Democracy (with one city & Shakespeare). 100% tax in Democracy yields more gold than taxes in any other gov't.
Progress was closely linked to the slow rate of spy producion (one per day, max, with one city), inherient limitations of a small engineer force, and to a lesser extent, health of combat units.
The pattern of destruction reminded me of a toxic biological culture, with my capital as the source of the toxin. The dots that represented the enemy cities in the overview map began to dissappear from nearby my own city at first, then outwards after that. Huge tracts of land, uninhabited. It almost seemed eerie as my deadly spies and small army used the winding RR to military wiz past the extinction... on the way to the next target, or to return to my city for repairs.
